(a) Elastic modulus, G′, plotted as a function of temperature for (●) Chi/Aga-1+Fe5%, (▲) Chi/Aga-1.5+Fe5% and (▼) Chi/Aga-2+Fe5%. Dashed lines show the determination of the melting temperature, Tm, of the gel. (b) Inset image corresponds to the variation in G´ as a function of agarose concentration for Chi/Aga ferrogels loaded with different concentrations of ferrofluid (() 0% (w/v); (■) 2% (w/v) and () 5% w/v)
